Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing nucleic acid decontamination methods are inadequate for sensitive environments, often using harsh reagents that are difficult to handle and do not consistently remove nucleic acids from surfaces, and they fail to maintain integrity of other biomolecules.
Innovation Solution
Utilizing amidated pectins with amino groups to flocculate and precipitate nucleic acids, either in solution or bound to solid supports, effectively rendering them unsuitable for amplification.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If harsh reagents such as sodium hypochlorite or psoralens are used for decontamination, then nucleic acid removal capability is improved, but handling difficulty and corrosiveness increase
Solution Approach 1:
The patent changes the chemical parameters of the decontamination agent by using amidated pectins with amino groups instead of harsh reagents like sodium hypochlorite. This parameter change maintains nucleic acid binding capability while improving safety and ease of handling, as the amidated pectin forms a biocompatible polymer that can effectively bind nucleic acids without the corrosive properties of traditional reagents.
Solution Approach 2:
The patent employs a composite material approach by creating amidated pectin derivatives that combine the polysaccharide backbone of pectin with amino groups. This composite structure provides both the structural integrity needed for effective nucleic acid binding and the chemical functionality (amino groups) for selective interaction with nucleic acids, while avoiding the harsh properties of conventional decontamination agents.
2Reliability
If bleach or similar reagents are used for decontamination, then nucleic acid removal is achieved, but integrity of other biomolecules is compromised
Solution Approach 1:
The patent applies local quality by designing amidated pectin with specific amino groups that are localized to interact selectively with nucleic acids. The amino groups on the amidated pectin structure provide specific binding sites for nucleic acids through electrostatic interactions, while the rest of the polymer structure remains biocompatible and does not damage other biomolecules, achieving selective decontamination.
Solution Approach 2:
The amidated pectin acts as an intermediary substance that mediates between the need for effective nucleic acid removal and the protection of other biomolecules. The amino groups on the amidated pectin serve as the active intermediary sites that specifically bind nucleic acids, while the polysaccharide backbone provides a biocompatible framework that prevents damage to proteins and other sensitive biomolecules.
3Reliability
If conventional decontamination solutions are used, then some nucleic acid removal is achieved, but consistent and reliable results in sensitive environments are not produced
Solution Approach 1:
The patent extracts the essential decontamination function from complex multi-step protocols and consolidates it into a single amidated pectin treatment. By isolating the key mechanism (amino group-mediated nucleic acid binding) into one versatile reagent, the patent eliminates the need for multiple sequential cleaning steps while maintaining reliable decontamination performance in sensitive environments.
